Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an automatic dial device having a line selection function included in a telephone, a facsimile, or the like.

<Prior art> With the privatization of Nippon Telegraph and Telephone Public Corporation (NTT), Dentsu No. 2, Nippon Telecom, and high-speed communication established new telephone lines one after another. Since these lines have different call charges depending on the location area of the other party and the time zone of the call, there is an advantage that you can make an efficient call if you select a line with a low charge.

It is possible to connect to each line by dialing by adding a 4-digit line selection number to the beginning of the conventional telephone number, and the first exchange of NTT that received this dial will connect to the other line number corresponding to the line selection number. Since it is connected to the circuit switch, it is possible to talk on the connected line after that.

At the beginning of the establishment of these lines, the line selection operation was entrusted to the operator, but in recent years an automatic line selection element (abbreviation: NCC) for automatically performing this has been developed and installed in telephones and facsimiles.

<Problems to be solved by the invention> By the way, this automatic line selection element (hereinafter referred to as NCC) is
There is the following problem because it is set to operate for all input phone numbers.

Depending on the line, the low rate system for nights, weekends and holidays may not be adopted. If this is not taken into consideration and the line is automatically selected only based on the area and time, a call may be made on a high-priced line.

The charge rate for each line is not the same, and the difference in charges between short-term calls and long-term calls differs from line to line. If this is not taken into consideration and a line is automatically selected only based on the region and time, and for example, facsimile communication is performed for a long time, the call charge may increase as a result.

In order to solve the above problems, an object of the present invention is to provide an automatic dialing device which prohibits a line selection operation as needed by a simple operation of an operator and allows a telephone call or communication with an NTT line with less risk. It is what

<Means for Solving the Problems> The automatic dial device of the present invention includes an input unit for inputting at least a special code and telephone number data, a detection unit for detecting the special code from the input data, and an input telephone number. A buffer that holds data, a calling unit that sends the telephone number data that is held in the buffer based on a call start instruction, and the telephone number data that is sent from the calling unit When there is a line selection unit that determines the optimum line from multiple types of lines based on the location area and the current time, and sends out the telephone number data input together with the line selection number data to the line, when the detection unit detects a special code The line selection unit is characterized in that the telephone number data transmitted from the calling unit is directly transmitted to the line without performing a predetermined operation.

Further, in order to improve the operability, the automatic dialing device of the present invention has an input unit for inputting a special code consisting of at least a predetermined number of numeric data and telephone number data, a buffer for holding the input data, and a buffer held in the buffer. Display unit that displays the data, a detection unit that detects a special code from the input data, a calling unit that sends the telephone number data held in the buffer based on the calling start instruction, and a sending unit that sends the calling number data. A line for inputting the telephone number data to be input, determining the optimum line from a plurality of types of lines according to the other party's location area corresponding to the telephone number data and the current time, and transmitting the telephone number data input together with the line selection number data When a special code is detected by the detection section, a numeric value data corresponding to the special code among the data held in the buffer is selected by a predetermined key. Characteristic data is replaced with character data, and the line selection unit is made immobile so that the telephone number data sent from the calling unit is sent to the line as it is.

<Operation> In the automatic dialing device according to the present invention, when a special code for prohibiting the operation of the line selection unit is input at the beginning of the other party's telephone number, the detection unit detects this and is controlled to perform a predetermined operation. Therefore, the line selection unit can be easily set to the immobile state.

<Embodiment> FIG. 1 shows an internal configuration diagram of an automatic dial device of the present invention and peripheral devices thereof, in which 1 is a dial key for inputting a special code and a telephone number, and 2 is a telephone which has been input. A calling key 3 for instructing to send out the number data to the line, a special code detecting unit (hereinafter, referred to as a detecting unit) for detecting whether or not a special code is included in the data input from the dial key 1, 4 Is a buffer for holding the data input from the dial key 1, 5 is a display unit for displaying the data held in the buffer 4, and 6 is a caller which sends out the telephone number data held in the buffer 4 when the call key 2 is pressed. It is the calling department. 7A is a changeover switch for switching whether or not to input the telephone number data from the calling unit 6 to the following NCC based on the instruction of the detection unit 3, and 7B is the destination area and the current time corresponding to the input telephone number data. The optimal line is determined from multiple types of lines, etc., and the telephone number data input together with the determined line selection number data is sent to the line.
Reference numeral 7 denotes an NCC, which is a line selection unit including the changeover switch 7A and NCC 7B. Reference numeral 8 is a timer for supplying the current time to the line selection unit 7, and 9 is a telephone line network control unit for controlling connection of telephone number data to the line and switching of line connection to TEL 10 and FAX 11 after the line connection is established.

With the above configuration, the key input for setting the NCC7B in the immobile state and its display sequence are shown in the flowchart of FIG.
This will be described with reference to the figure.

In order to set the NCC7B in the immobile state, it is necessary to enter a special code of two digits at the beginning of the telephone number. In this embodiment, this characteristic code is "09" and the telephone number is "07435-3-552".
1 ”.

When the dial key 1 is operated to input “0” and “9”, the data is held in the buffer 4 and the display unit 5
Is displayed in. The detection unit 3 constantly monitors this input state, and when "0" is input thereafter, it detects that the feature code has been input and is input before the currently input "0" and held in the buffer 4. The numerical data of “09” is “N”
And the information indicating that the feature code has been input is output to the line selection unit 7. As a result, the line selector 7 switches the changeover switch 7A to the caller 6 and the NCU 9
Is switched to a direct connection, or information (prohibition code data) indicating that the feature code has been input is set inside. The so-called telephone number data of "0" and "743535521" input after the input of the feature code is sequentially held in the buffer 4.

Next, the calling operation performed based on the input feature code and telephone number data will be described with reference to the flowchart of FIG.

When the calling key 2 is operated while the telephone number data is held in the buffer 4, the line selector 7 is set to switch the switch 7A based on the prohibition code data.
And the NCU 9 are switched to be directly connected (this operation is not necessary if already switched), and the calling section 6 converts the telephone number data held in the buffer 4 into a corresponding calling signal and sends it. Therefore, since the telephone number data sent from the calling unit 6 is supplied to the NCU 9 via the NCC 7B, the NCC 7B does not perform the line selection operation. If the characteristic code is not input at the telephone number input stage, the changeover switch 7A remains in the state shown in FIG. 1, so that the telephone number data in the buffer 4 is input to the NCC 7B via the calling section 6 and a predetermined number is input. Then, the telephone number data is sent to the line via the NCU 9 together with the line selection number data determined by performing the line selection operation of.

In the above embodiments, the special code is "09", but the present invention is not limited to this, and a combination of numbers not existing in the telephone number or a combination of "#" and a number is also possible. The present invention is also effective when a speed dial key and a one-touch dial key are used as means for inputting a telephone number.

<Effects of the Invention> According to the present invention, it is possible to set the prohibition of line selection by using a dial key that is normally provided, and a special code consisting of numbers is provided as a method for surely informing the operator of the setting state. Is configured to be displayed on the dial display portion after being replaced with a predetermined character when the character is detected, a dedicated key and a display portion relating to the prohibition setting of the line selection are not required, and the cost can be reduced.
